Answer:
y = -1/2x - 2.5 or y = -0.5x - 2.5
Step-by-step explanation:
You want to first find the slope of this perpendicular lie which is the negative reciprocal.
Original slope = 2
New slope = -1/2
So now you want to plug in the (5,-5) to find the y-intercept
y=-1/2x+b
-5 = -1/2 (5) + b
-5 = -2.5 + b
b = -2.5
So, your new equation is y = -1/2x - 2.5

Answer:
i
Step-by-step explanation:
19 thousands is 19 x 1000 = 19,000
7 tens is 7 x 10 = 70
19 thousands plus 7 tens is 19,000 + 70 which is 19,070.
